We provide solutions and system integration with Operations and Maintenance (O&M) in mind to meet the needs of our valued customers for our water treatment projects. Our expertise is focused on desalination, water reuse and wastewater treatment.

Keppel Marina East Desalination Plant, Singapore

The Keppel Marina East Desalination Plant is Singapore’s fourth desalination plant, the first of its kind that can treat both seawater and freshwater from the Marina Reservoir by using reverse osmosis and other advanced membrane technology. It is owned and operated by Keppel Seghers under a design, build, own and operate (DBOO) arrangement with PUB, Singapore’s national water agency. The plant is able to produce up to 137,000m3 of fresh drinking water daily, and will supply product water to PUB over a 25-year concession period from 2020 to 2045.

The plant features a sleek modern design that breaks away from those of conventional water treatment plants and is the first to feature green spaces that can be used by the public for recreation. The plant’s water treatment equipment is located underground, and features treatment processes which utilise advanced membrane technologies, direct coupling and ultraviolet primary disinfection for space saving with a compact footprint of less than 2.4 hectares.

In 2018, KMEDP was awarded the Yuan Ye Award (园冶杯) (Gold Award) by the Yuan Ye Award International Corporation. In October 2019, KMEDP became the first industrial plant in Singapore to be awarded the ABC Waters Certification (Gold) by PUB, in recognition of its outstanding design features and green, sustainable elements such as the 20,000 square metres of open green rooftop space for community recreation, and environmentally friendly features such as rainwater harvesting.

Ulu Pandan NEWater Plant, Singapore

Keppel Seghers Ulu Pandan NEWater Plant commenced commercial operations in March 2007 with a production capacity of 148,000 m3 per day. It is one of Singapore’s largest NEWater plants and also one of the largest wastewater recycling plants in the world.

NEWater is treated used water that has undergone stringent purification and treatment using advanced dual-membrane (microfiltration and reverse osmosis) and ultraviolet technologies. The ultra-clean NEWater can be used in wafer fabrication, non-potable applications in manufacturing and air conditioning cooling towers in commercial buildings.

Awarded by PUB in early 2005 to design, build, own and operate the plant for 20 years under the Public Private Partnership initiative, the plant meets the demand from industrial and commercial sectors in the western and central regions of Singapore.

In 2016, Keppel Seghers embarked on a treatment capacity upgrading project and installed a third-stage reverse osmosis (RO) system that recycles the reject water from the second-stage RO system. The upgrading works boosted the plant's design and contracted capacity to 162,800 m3 (35 million gallons) of NEWater daily, up from 148,000 m3 (32 million gallons) previously.

Sino-Singapore Tianjin Eco-City (SSTEC) Water Reclamation Centre, China

This project utilises a unique patent developed by Keppel Seghers, through its joint venture company, which recovers excess pressure in the reverse osmosis stream for recycling effluent to achieve energy savings.

The project was developed under a 25-year concession Build-Own-Operate-Transfer (BOOT) arrangement by 40-60 joint venture between Keppel Infrastructure and Tianjin Eco-City Investment and Development Co.

The SSTEC project serves all of the Eco-City's landscaping and non-potable water needs, comprising wastewater treatment (Class 1A WWTP: 100,000m3/day, with future expansion of 50,000m3/day) and water reuse (21,000m3/day, with future expansion of 21,000m3/day).

Doha North Sewage Treatment Works, Qatar

The Doha North Sewage Treatment Works (DNSTW) is the largest greenfield wastewater, water reuse and sludge treatment plant in the Middle East Situated at Umm Salal Mohammed in Qatar and was designed, built and operated (DBO) by Keppel Seghers from 2015 to 2020. With a peak design capacity of 439,000 m3 per day of high-quality reclaimed water for reuse, the DNSTW is able to serve a population of around 900,000.

The facility marked several “firsts”, being the first wastewater treatment facility in Qatar to use advanced membrane and ultraviolet treatment to reclaim high-quality water for non-potable use. It is also the first facility in the Middle East with a comprehensive odour control system to minimise the impact on the surrounding environment. The DNSTW is also the first to be equipped with a modern sludge treatment process to deal with a large amount of sludge from all sewage treatment works in Qatar.
